COIN-CONTROLLED MECHANISIVI.

Application led January 10, 1921. YSerial No. 436,308.

T 0 all whom t may concern.'

Be itknown that I, MASON L. VILIJAisrs, a citizen of the United States, residing in the city of 1Weleetka and State of Oklahoma, have invented new and useful Improve-l ments in VCoin-Controlled Mechanisms, of which the following is a specification, reference being `had to the accompanying drawin i g'lhis invention pertains to coin controlled mechanisms, and theobject is to provide a relatively simple mechanism for this purpose, and which will be at the same time efficient for the purpose intended. Y

Another object is to provide such mechanism in a form which may be readily'set or adjusted to be operable by the insertion of one, two, three or more coins, as desired.

In the drawings:

Figure 1 is a side elevation of the coin receiving element, the casing being shown 1n longitudinal section.

Figure 2 is an end View of the coin re-` tween the points 2 and 3 a shaft 4, one end 5 of whichprojects outside the case 1. A plurality of spools 6, 7, 8, 9, 10 of equal diameter are rotatably mounted in alignment upon the shaft 4. IThe outer spool 6 is sufficiently long to afford a suitable journal through the case at the point 2, and to the end thereof is rigidly joined the hand lever 11. The inner end 6 of the spool 6 extends within the case a distance substantially onehalf the width of the coins 12 to be used in recesses; and each of the spools exceptthe inner spool 10 carries a pin 17 upon its left hand end adapted to play into and slidingly engage the recess of the spool at its left, and to lock against the shoulders 15 and 16 thereof as the'spools are rotated back and forth on the shaft 4. rIwo coin ngers are rigidly mounted upon each spool, and are represented at 18-19, 20-21, asf-2a, srt-.25, 26-27 respectively. These fingers are slightly less in width than the lengths ofthe spools so as to allow the spools to rotate freely, while the fingers 18-19 are about half the width of the others, and all are equally spaced apart so as to freely receive the coins 12. These fingers are so aligned relative to the shoulders 15 that when the pins 17 are all turned back anti-clockwise against these shoulders 15, the coin fingers will all stand in perfect alignment so as to permit the coins 12 to be slid straight through to the last set of fingers 26-27. lThe fingers are shorter than the width o-f the coins 12 so as to leave the coins protruding beyond the ends of the fingers, and the inner faces of the fingers are notched as shown at 28 so as to engage andY hold slidingly in place an adjustable coin stop 13 adapted to slide back and forth along the fingers. A coin slot 29 is out through the-case 1 in alignment with the coin fingers. A coil spring 30 is set within an annular recess 31 formed in the outer end of the spool l 6 and engages the bearing 32 outwardly and the said spool 6 inwardly, and thus normally turns and holds all the spools back with the pins 17 against the shoulders 15 and the coin fingers and slot 29 .all in alignment, ready for the insertion of the coins 12. A stationary curved guard 56 is mounted over the coin fingers and extended downwardly to the right, as lshown in Figure 2.

A trigger shaft 33 is journaled in the case 1 to the right ofand parallel to the spool shaft r. This trigger shaft is square in cross section intermediate of its journals,

and a trigger arm 34 is slidingly mounted on this squared shaft through the correspondingly squared hole 35, and the free end 36 thereof'is extended over immediately adjacent the row lof-spools aforesaid, and adapted to be engaged by any of the coins 12 deposited in the coinfingers. Thus as one, two, three or four coins may be deposited and slid along into `the aligned coin fingers, the trigger arm 34 may be moved along the shaft 33 until it is immediately opposite the innermost coin andso operable only by that coin as it is rotated or tuiiied down to the right. The arm 34 may be locked in any position on the shaft 33 by a set screw 37. At any convenient point on the shaft is permanently mounted a lever 38 carrying a pawl 39 adapted to engage the ratchet 53 of the wheel 40 on the shaft 41. At the outer end of the shaft 41' is attached aiioperating le-l ver (not shown), and this lever, ratchet wheel and shaft control the movements of any attached mechanism or machine. A coin chute 42 is mounted underneath. A

fratchet and pawl mechanism (not shown) .Y tate together.

prevents the shaft 41 being turned backward oranti-clockwise.

A curved, fiat spring 44, with studs 45 and 46 at its ends, is mounted at 47 over a rounded part of the shaft 33 carrying the shallow friction cups 48 and 49, the cupsk being so positioned that as the arm 34is rocked up or down thus engaging or releasing the pawl 39 the studs will alternately engage the cups and so frictionally hold the arm. in either position until it is forcibly rocked to its other position. Any of the coins 12 serve to rock the arm 34 downward by engaging the end 3G; but it is rocked upward by means of a rod 5() having its inner end formed into a loop 51 which slidingly engages the cam 52,

disposed oppositely to the ratchet 53 while the outer end is formed vinto a hook 54 which engages the transverse slot 55 in the lever 38. Thus when the trigger arm k34 is depressed the pawl 39 is clear of the. ratchet 53 and the wheel 40 may be rotated clockwise onerevolution; but this same revolution causes ,the

cam 52 tov draw the hook 54 and lever 38 inwardly and so again locks the pawl 39 into t-he ratchet 53.

In operation the adjustment'stop 13 is adjusted upon the coin fingers so that. only the predetermined and desired number of coins can beslid into the aligned coin fingers, as may be required to operate the mechanism; andthe trigger arm 34 is adjusted to meet the innermost coin of the number inserted. If it lis desired .that the mechanism be operable through the insertion of only one coin, as a penny, the coin stop 13 is moved outwardly along the coin fingers to ,a point admitting of the insertion of only one such coin and the trigger arm 34 is; adjusted to meet that coin as it is turned down to the right. This firstcoin would spanthe first set of coin tingers 18-19 and entendhalfway into the second set of fingers 20-21,

' thus locking all these fingers so theywill ro- On turning the handle V11 clockwise, the coin is turned down to the right and strikes the triggt-ir arm 34, rocking it back ,and releasing the ratchet 40 so that the shaft'41 may be rotated by any suitable .Z smeans, such as a lever.

anism may be adjusted for operation bytwo,y

Vthree ormore coins, by setting the stop13 l and Similarly. the mech-4 trigger arm 34 accordingly, it being understood that the trigger arm is operated always by the innermost coin. Ilien the coin fingers are turned down past the trigger arm 34 the coins drop into the chute 42 and the coin fingers are automatically returned to their original aligned position by the action of the spring 30. rIhe arm 34 however is held in its downward position by the stud 45 in the cup 48, until the lever is rotated.

It will be noted that by virtue of the first two coin fingers 13-19 being half the width of the coins 12, while the others are thefull width of the coins, as said coins are slid into place between the aligned fingers, said coins will successively overlap the fingers,l so that each coin vwill engage two sets of fingers and lock them for joint rotation'as the lever 11 yis turned clockwise. The' purposeV of such arrangement is to force the insertion of the required number of coins to operate the mechanism. As the coins are inserted they interlock the fingers andspools so that they all rotate together and the innermost Vcoin engages the trigger arm. Should less than the required number jof coins be inserted, they would not interlock the necessary number of fingers, and would not extend to the trigger arm, and hence turning the lever 11 would merely result in rotating the spools without actuating the mechanism. Y Y

This mechanism may be adapted for use upon any machine operablethro'ugh the deposit of coins; andrwhile I have hereindescribed a certain-specific method of constructing and assembling the elements of my invention, it is understood same may be` va riediii minor details, not departing from the vspirit of my invention as definedin the appended claims. j Y
